Lock timeout exception on KM operations

45 Views

Hello,

every once in a while, I see a couple of error messages like this in my logfile:

Message : java.sql.SQLException: Lock timeout exceeded for <documents>, wait time = 60129

at com.sapportals.wcm.repository.service.appproperties.persistence.SQLCallsOpenSQL.lock(SQLCallsOpenSQL.java:1798)

at com.sapportals.wcm.repository.service.appproperties.persistence.SQLCallsOpenSQL.delete(SQLCallsOpenSQL.java:180)

....

Location : com.sapportals.wcm.repository.service.appproperties.persistence.Persistence.Lock timeout exceeded for <documents>, wait time = 60129

generated by users checking in or uploading documents or even by TREX when indexing documents.

After a few minutes everything works well again.

What does this message mean? Is this a performance problem? Or a database problem?

Any help on this is appreciated!

Regards, Thomas
